Energy Management

<p>Using energy to create heat that no one uses is the same as throwing money out the window. Not only is it unnecessary and bad for the environment, but you might also be caught short when the electricity bill arrives.</p>



<h2 class="wp-block-heading" id="h-get-an-overview">Get an overview</h2>



<p>In the past, it might have been difficult to find a good midpoint between icy outdoor temperatures and stuffy indoor heat in the winter, but this is no longer the case. In Europe, buildings account for around 40% of total energy consumption. This means that it pays to take better care of the energy we create. Here are some tips for sending you on the path to greener consumption:</p>





<h2 class="wp-block-heading">1. Be aware of energy consumption</h2>



<p>Enova's research shows that simply being aware of energy consumption can help you save up to 5%. Additionally, getting something down on paper makes it easier to identify and implement energy-saving measures. How much energy do we want to use? How many emissions will we save the environment from? </p>



<h2 class="wp-block-heading">2.&nbsp;Evaluate the technical system</h2>



<p>Failure or improper use of technical systems often leads to increased energy consumption. Assessing the system's condition is the first step in identifying energy loss. Continuous monitoring is a good investment for your wallet and the environment – you'll notice discrepancies sooner! &nbsp;</p>



<h2 class="wp-block-heading" id="h-3-use-an-energy-management-system">3.&nbsp; Use an energy management system</h2>





<p>Energy data that requires manual handling gets forgotten after a while. An&nbsp;<a href="https://kiona.com/products/energinet/">energy monitoring system</a>&nbsp;(EOS) can be a good tool for fully understanding the system's energy consumption. <em> </em></p>





<h2 class="wp-block-heading" id="h-4-rehabilitate-old-buildings">4.&nbsp;"Rehabilitate" old buildings</h2>



<p>Old buildings often use more energy, but this doesn't mean you should build new ones. There are many ways to optimize old systems, for example, with&nbsp;IWMAC's add-on Smart functions. </p>



<p>In older buildings, you will often find an old central heating system from one supplier and a heat pump from another. Our SCADA solution becomes the "interpreter" between these systems and provides easy integration with everything you need to optimize.  &nbsp;</p>



<h2 class="wp-block-heading" id="h-5-monitor-your-energy-consumption">5.&nbsp;Monitor your energy consumption</h2>



<p>If you have a system that doesn't have some form of load control, you're probably using more energy than necessary. If your energy consumption suddenly increases, your energy bill can get expensive, something you'll be paying for for a long time afterward. With a&nbsp;smart guard, you can ensure your spending is always below the limit. This way, you can easily avoid throwing energy out the window.</p>





<h2 class="wp-block-heading" id="h-6-heat-where-needed">6.&nbsp;Heat where needed</h2>



<p>Zone management is worth its weight in gold when discussing saving energy and is more relevant than ever. There is a big difference between the heat and ventilation required when the building is half full and when it's jam-packed.</p>



<p>You can set up IoT sensors that provide information about how the building is used. The SCADA system can then automatically&nbsp;stop heating the parts of the building that are left empty without the need to lay a single cable. </p>





<h2 class="wp-block-heading" id="h-7-control-using-calendar-and-weather-forecasts">7.&nbsp;Control using calendar and weather forecasts </h2>



<p>Holidays and weekends are the typical times we know the building will be empty. It pays to keep a good base temperature while also saving energy. Afraid that the building won't be warm enough tomorrow morning? You can easily solve this with&nbsp;calendar-based control. </p>



<p>It's also nice to manage the building according to the weather, not what it is&nbsp;right now. Why not turn off the temperature in the building three hours before it becomes warm outside? As such,&nbsp;forecast-based control&nbsp;is a clever way to prepare the installation. </p>





<h2 class="wp-block-heading" id="h-why-save-thousands-on-your-electricity-bill">Why save thousands on your electricity bill? </h2>



<p>… other than for the money saved? There are many reasons to put energy efficiency on your list of priorities. &nbsp;</p>



<p>We spend a lot of time indoors in the Nordic countries. Incorrect temperature is one of the most significant contributors to poor indoor air quality. Ever complained about "bad" air? Often this means it's too hot. Increased heat also makes us more vulnerable to pollutants in the air, and the ventilation system usually has to work twice as hard. &nbsp;</p>



<p> Saving energy also benefits the environment and helps us to reduce unnecessary emissions and meet our sustainability goals. It is also good for your body, soul, and conscience.</p>

Are you wasting your energy? 7 tips for lower energy bills

Let IWMAC and it's smart functions help you

Improved energy efficiency

<p>Today, most cooling systems are equipped with heat recovery. Heat recovery refers to capturing and reusing waste heat that would otherwise be lost to the environment. After the primary function of the cooling (or heating) capacity has been performed, the excess heat can be reused to either improve the efficiency of the heat exchange process or used elsewhere.</p>



<p>For example, by taking care of the cooling systems' heat recovery, the excess energy can heat the store and hot water instead of being cooled on the roof. This process will reduce the need to buy electricity from the grid and provide a better operating economy. The savings in energy costs can be as much as 30% when switching to carbon dioxide refrigerant.&nbsp;</p>



<h2 class="wp-block-heading" id="h-improved-energy-efficiency">Improved energy efficiency </h2>



<p>Understanding heat recovery and regeneration is essential for improving energy efficiency and sustainability in various sectors. Implementing these techniques can lead to significant economic and environmental benefits. Unfortunately, many do not have good enough systems to notify them or override their heat regenerator if a need elsewhere in the building appears.&nbsp;</p>

<h2 class="wp-block-heading" id="h-let-iwmac-and-it-s-smart-functions-help-you">Let IWMAC and it's smart functions help you</h2>



<p>Heating a store can be expensive. Therefore, it's essential to have a heat recovery unit that operates only when needed. With its smart function <a href="https://kiona.com/products/iwmac/smart-functions/forecast-based-control">forecast control </a>and heat recovery, IWMAC ensures you can extract as much excess heat as possible from refrigeration machines. Through adjustments, grocery stores can harness the excess energy from refrigerated counters and convert it into heat.</p>



<p>It has plenty of smart functions, like alarm monitoring. If the heating or cooling system is using an unusual amount of energy, you can receive alarms of non-conformances. With<a href="https://kiona.com/products/iwmac/alarm-monitoring-24-7"> Alarm Monitoring 24/7</a>, we will help you filter and handle the alarms and inform you only when a critical alarm occurs.</p>



<p><a href="https://kiona.com/products/iwmac/smart-functions/smart-guard">The smart guard</a> ensures that you use less energy and pay less than necessary. It also monitors your consumption minute by minute and ensures that you don't exceed your limits.</p>



<p>IWMAC is our SCADA system, providing a hybrid web-based solution to manage all your technical installations, including refrigeration, freezing, buildings, and manufacturing. The fully independent platform can integrate all technical systems regardless of brand, supplier, or age.</p>
